Finally t all ; branchlets slender ; leaves scattered, lanceolar-sickleshaped, exceptionally 

 verging into an oblong form, of equal color and generally somewhat shining on both sides ; their 

 lateral veins rather prominent, crowded, pinnately spreading, the circumferential vein somewhat 

 removed from the edge of the leaf ; oil-dots generally much concealed ; umbels axillary or lateral, 

 solitary, on slender stalks, usually bearing from 4 to 8 flowers ; stalklets thin, much shorter than 

 the whole calyx ; lid variously longer than the semiovate or hemispheric tube of the calyx, often 

 much elongated, varying from subulate-conical to semielliptical ; stamens all fertile ; filaments not 

 distinctly inflexed before expansion ; anthers nearly oval, bursting with longitudinal slits ; stigma 

 not dilated ; fruit somewhat roundish in outline, not large ; rim broad, protruding, convex ; valves 

 high-exserted ; the latter four, rarely three or five, almost deltoid or semilanceolar ; seeds small, 

 all without any appendage, the sterile seeds very narrow. 



From the Gilbert- and Burdekin-River to Gippsland (F. v. M.), ascending to New England, 

 advancing inland to the Gwydir and some other western streams of New South Wales, but never 

 very far removed from literal regions, traced already by R. Brown northward to the Northumber- 

 land-Islands, occupying generally humid flats or growing around swamps and lakes or along 

 watercourses, never on saline ground or saltwater-streams. A good-sized tree when well 

 developed, but seldom exceeding 100 feet in height, and generally not so tall, although heights of 

 160 feet are on record ; becoming stunted when occasionally growing in rocky exposed localities. 

 Bark smooth, whitish or greyish ; but when especially towards the bottom of the stem the outer 

 layers remain persistent, they form somewhat scaly or thinly laminar flakes. Leaves of some 

 trees in general hardly exceeding half an inch at their broadest part, but otherwise gaining not 

 rarely a length to 8 inches or even more ; oil-dots sometimes copiously visible and transparent. 

 Umbels towards the end of the branchlets occasionally leafless, then constituting short panicles, 

 containing exceptionally as many as 18 flowers. Stalklets reaching a length of \ inch. Calyx- 

 tube not seldom shorter than any of those indicated in the illustrative plate. Lid sometimes 

 rather suddenly contracted above the base, often slightly curved ; rarely the lid almost semiovate 

 and but little longer than broad. Filaments whitish, hardly or slightly flexuous in bud. Style 

 elongated, thickened towards the summit. Totaf length "ofTruit 4-5 lines. 



Small seedlings have opposite almost oval leaves, on very short stalks ; but soon the leaves 

 become scattered, longCT^aJke^ahSTmorelanceolar (see fragm. phytogr.^ustr. vii. 44). 



Sir James Smith chose the specific name in allusion to the generally cylindric-pointed lid of 

 the calyx. 



Although in many localities designed " Eedgum-tree," this Eucalyptus passes also as 

 "Flooded Gumtree " and under the quite misleading names "Grey Gumtree" and "Bastard-Box- 

 tree." Its close affinity to E. rostrata was discussed, when that species was treated in this work ; 

 indeed, as then remarked, both might be regarded as forms of one species, and one illustration 

 would only have been given for both, did not E. tereticornis claim a special place as one of the 

 earliest of congeners described, and did not E. rostrata on account of its leading technologic value 

 need prominent consideration ; otherwise each of the illustrated plates is assumed to represent
